Trigger just in case.

Ok, I have an issue with derealization, with two main triggers:

1. Out in social situations. Doesn't really matter who I'm with, or how I'm feeling...I think subconsciously I must feel uncomfortable with my surroundings. Everything around me starts to feel unreal, people, places, things...everything seems unreal. Like I am the only "real" thing there. It's so surreal. And I am aware when it's happening, too, but that doesn't help. I can be stuck in this "state" for several hours. I usually have to be home and in my "normal" environment before I "snap back" into reality.

2. When I'm feeling extremely depressed, I withdraw into myself and nothing around me seems real.

Can anyone relate to this? Any replies and advice on how to overcome this would be greatly appreciated. Thank you!
